In today’s world, learning skills like coding is more important than ever. But many students struggle to find the right guidance, support, and environment to grow. That’s where Master Coding Org (MCO) comes in. Master Coding Org (MCO) was created with a simple mission: Make learning coding accessible, collaborative, and practical for everyone. Instead of learning alone, MCO focuses on building a c
More rules should mean better output. That's the intuition. I spent weeks building a comprehensive CLAUDE.md — 200 lines covering naming conventions, security rules, error handling, architectural patterns, import ordering, type safety requirements, and more. I was proud of it. I'd thought through every scenario. Then I scored the output. 79.0 / 100. My carefully crafted documentation was actively
r/startpages Is the Most Underrated Firefox Community You're Not Using If you care about browser customization, there's a subreddit you probably haven't found yet: r/startpages. With 35,000+ members, it's a community of people who genuinely care about what appears when they open a new browser tab.

Midnight. Blank screen. One question: The problem nobody talks about What Good Deed Board actually does "She'd been putting off that errand for three days — her knees were bad and the traffic frightened her.

A sponsor’s perspective This blogpost is written on the heels of a few amazing weekends spent knee-deep in students in Toronto and Los Angeles at Hack Canada and LA Hacks, engaging almost 2000 students in person in total. Managing a sponsor track, I have some thoughts on good ways to present yourselves when angling your project towards a sponsor prize. For those not as familiar with how student ha
Have you ever looked at code you wrote six months ago and thought: "Who wrote this monster?"? Relax, it happens to all of us. In software engineering, writing code that a machine understands is the easy part. The real challenge is writing code that other humans (including your future self) can understand, maintain, and scale. This is exactly where Software Design Principles come into play. In this
Part 1 of 5 in The New Engineering Contract — what it means to lead engineers when AI is doing more of the coding. SWE-CI tested 18 AI models across 71 consecutive commits. Most broke something on commit 47 they'd already broken on commit 1. That's not an intelligence problem. That's a learning system that isn't learning. A paper made me uncomfortable this month. Not because of what it found about
